This invention relates to a time register and recording device for useparticularly in indicating lapsed time in telephone conversations.

One of the objects of the invention is to providea device of thischaracter which shall consist of a few parts, not apt to get out oforder, which shall be ready for use at short notice and which may beconstructed at small cost.

Further and more specific objects, features and advantages will clearlyappear from the detailed description given below, taken in connectionwith the accompanying drawing which forms a part of this specification.

' In the drawing;

Fig. 1 represents a perspective view of a device embodying theinvention.

y Fig. 2 represents a plan view thereof partially broken away. U

Fig. 3 represents a transverse section along the line 3-3 of Fig. 2.

Fig. 4 represents a longitudinal section along line 4-4 of Fig. 2. t

Fig. 5 represents an enlarged detailed View of a part of the mechanismfor transmitting motion from 'the clock mechanism to the registeringmechanism.

Referring now more particularly to the drawing, 1 represents asubstantially rectangular oblong metal casing on top of which is mounteda telephone record pad 2. This vpad is adapted, as here shown, for usewith the telephone for long distance calls, and has printed thereon thename of the month, the place called, the date and the lapsed time. Thispad occupies the top of the casing, eX-

cept for a space along the edge which isgraduated in time intervalsbeginning at zero, then three minutes and thereafter for each minute uptothirty minutes.

In order to register the time so that the indicated registration can berecorded on the pad, a pointer 8 formed as a handle is provided. Thispointer is intended to be grasped by hand and moved to the zero point onthe time interval scale, when the telephone conversation is started. Thelower limb 4 of the pointer passes through a slot 5 in the side of thecasing 1, which slot is slightly longer than 1929. Serial N0. 370,564.

the time interval scale mentioned. The lower leg 4 has its extremitybent downwards and attached by a rivet to a band 6. This lower limb 4 isalso provided with a guide-way 7, through which projects a guide rod 8suitably supported at either end of the casing 1.

The band 6 is driven by clock mechanism 9 and adapted to be wound by key10, furnishing motion to drive the band through a gear 11. The gear 11meshes with a gear 12, mounted on a spindle 13, suitably supported atthe top and bottom, respectively7 of the casing 1. Mounted above thegear 12 is a pinion 14 provided with teeth 15 adapted to engage incorresponding holes 16 in the band 6. Below the gear 12 is a coil spring17 having one end 18 attached to the floor of the casing 1, the otherend 19 being free.

The pulley 14 is provided with a slipclutch 20. Vhen the pointer 3 is inthe position shown by broken lines in Fig. 2, and is being driventhrough the clock mechanism towards the end of the time scale marked 30minutes, the spring 17, wrapped around the spindle 13, allows the gear12 and the pinion 14 to move freely in the desired direction, that is,counter clock-wise. When the pointer has reached the upper limit of itstravel, which is provided by a pin 21 on the guide bar 8, it isnecessary for it to be returned to zero, in order to start registrationagainl In order to permit this, the gear 12 must be held against motion,while the pinion 14 must be allowed to move so that the band may moveover it and carry the pointer back to the desired position. This isaccomplished by the action of the spring 17 which holds the spindle 18against rotation in a clockwise direction, and also holds the gear 12which is attached to it against such rotation. The slip-clutch 2O on thepinion 14, however, allows this pinion to rotate on the spindle 13 andso the band can travel back with the pointer to the starting point. Astop 22 at the zero end of the bar serves to stop e the pointer at thestarting position.

After the telephone conversation is started, in case a disconnection orother interference occurs and it is desired to stop the timeregistration, the pointer may be stopped at any instant in its travel bymoving a button 23, located on top of the casing and having a studprojecting through the casing and connected to a sliding arm 24 providedwith a downwardly projecting lug 25 having a sur face for braking. Thissurface contacts with a corresponding braking surface on a wheel 2Gmounted above the pinion 14. A slot 27 in the casing allows the stud 23,and with it the arm 24, to move back and forth into and out of brakingposition. When moved to braking position, a spring arm 28, bent to forma recess, snaps over a pin 29 to hold it in that position. i e

When it is desired to operate the device, the telephone connection isrequested, the pointer is grasped by the telephone user and moved downto zero position, the brake having been released, if on, and the clockmechanism having, of course, been previously wound while waiting theconnection, the button 23 may be moved to hold the pointer at thestarting point. When the connection is made, the brake is released andregistration of the lapsed time proceeds, the pointer being carriedalong by the band 6 Yover the time interval scale accurately indicatingthe lapsed time. If there is a disconnection or other interference withthe communication, the button 23 may be immediately pushed to stop themovement of the pointer, and when connection is again reestablished, thebutton may be moved back to proceed. At the end of the conversation, thetime registration is noted, and the telephone user records on the padthe city called, with the date and time. This'pad then forms a recordwhich may be used for a large number of calls, say, for one month, andat the end of that month the calls reported by the telephone company maybe checked up to determine their accuracy. The use of a pointer forregistering the time in this way, and a pad which may be used for aconsidj erable period without changing the sheet, in-

sures that a proper record can be kept and seen at a glance, while atthe same time it is not necessary to insert a new sheet each time it isdesired to make a record of a call where a time recording instrument isemployed, as we are aware has been proposed.

the language or scope of any one or more of the appended claims.

`What we claim as new and desire to secure by Letters Patent, is:

l. The combination of a slotted casing adapted to support a memorandumpad, timing mechanism Within the casing, a guide bar within the casingnear the slot thereof, a collar slidable on said Guide bar andoperatively connected with said timing mechanism, and a pointer carriedby the collar and extending through the slot, the casing being providedwith a graduated scale adjacent the path of movement of the pointer, forcooperation with the pointer.

2. The combination of a casing capable of supporting a memorandum pad,clockwork timing mechanism carried therein, an endless belt driven bythe timing mechanism, a guide bar adjacent one stretch of said endlessbelt, the casing having a slot adjacent said guide bar, a collarslidable on said guide bar and secured to said endless belt and carryinga pointer which extends through the slot, and graduated markings on thecasing cooperating with said pointer.

3. The combination of a casing provided with a slot, clockwork timingmechanism carried by the casing, an endless belt driven by the timingmechanism, one-way clutch means associated with the drive for theendless belt for permitting reverse movement thereof, a guide baradjacent the slot and one stretch of the endless belt, a graduated scaleon the casing, and a pointer provided with a guide slidable on saidguide bar, the pointer extending out through the slot into cooperativerelation with the graduated scale.

In testimony whereof we have signed our names to this specification.

Accordingly our device is ready for instant use at any time.

Our device is a simple one with few parts to manufacture, and not apt toget out of order, and can be inexpensively produced.

While we have described our improvement in great detail and with respectto a preferred embodiment thereof, we do not desire to be limited tosuch details or forms since many changes and modifications may be madeand the invention embodied in widely different forms without departingfrom the spirit and scope thereof in its broader aspects. Hence wedesire to cover all forms coming within
